Best Practices for Henkel Lite-Lok 499
LITE -LOK 499 bonds well to many untreated surfaces. However, adhesion is often improved by surface preparation before bonding. The surface should be free of contamination such as dirt, dust, grease or oil. An alcohol wipe is suitable for cleaning most surfaces. Optimum strength is obtained by abrading the surface followed by a solvent wipe to remove any loose particles. Polyolefins must be corona treated, or flame treated before bonding.
LITE -LOK 499 is best applied by extruding the product onto the substrate to be sealed or bonded using a 16-20 gauge dispensing tip. Sufficient product must be applied to seal all gaps, and completely coat the part to be bonded or sealed. After dispensing onto the part, the product should be cured as soon as possible to prevent any pre-reaction with ambient light.
LITE -LOK 499 may be applied via a pressure pot, or piston pump dispensing system. All fittings and tubing used in the dispensing system must be opaque to light. Since the product is also moisture curable, all fittings and lines must be completely sealed against moisture. Compressed air used for dispensing should be dry to avoid introduction of moisture into the product.
The time needed for UV curing is a combination of many factors. Some of these are the following:
The thicker the substrate, the longer the exposure time needed for curing.
The more UV light absorbing that the substrate is, the longer the exposure time needed for curing. § The lower that the intensity of the UV light source is, the longer the exposure time needed for curing.
The farther the distance of the product from the UV light source, the longer the exposure time needed for curing.
Typically, LITE-LOK 499 will cure after a UV light exposure from five to ten seconds, when cured at or near the focal point of a high intensity UV light source. Moisture cure occurs at ambient temperature and humidity.
